ABSTRACT:
Process for increasing the resistance to corrosion and erosion of a vane of a rotating heat engine, which vane consists essentially of a ferritic and/or ferritic-martensitic base material, in that a firmly adhering protective surface layer consisting of 6 to 15% by weight of Si, the remainder being Al, is sprayed onto the surface of the base material using the high-speed process with a particle velocity of at least 300 m/s.
